17 If it's a polling commit-journal-to-disk behavior, there's certain to
18 be a configurable parameter somewhere to control the poll rate.
20 However, if it's doing that, then it probably has something it needs
21 to write to disk. That might be metadata updates. Have you tried
22 adding things to your mount parameters like 'noatime' or 'relatime'?
23 What about "data=writeback"?
